2. Hold the thermometer approximately 1-5 cm (0.4-2 inches) from the center of the forehead.
3. Press the Scan/Measurement button once.
4. The temperature reading will appear on the LCD display within 1 second, accompanied by a beep.
5. The backlight color will indicate the temperature status:

6.2 Switching Between Celsius (°C) and Fahrenheit (°F)

With the thermometer powered on and in standby mode, press and hold the Mode button for a few seconds until the unit changes from °C to °F or vice versa. Release the button when the desired unit is displayed.

6.3 Memory Function

To recall previous temperature readings, press the Memory button. Each press will cycle through stored measurements. The thermometer typically stores the last several readings.

6.4 Fever Alarm

The thermometer is equipped with a fever alarm feature. If the measured body temperature exceeds a predefined threshold (e.g., 37.4°C or 99.3°F), the display backlight will turn red, and an audible alarm may sound, indicating a potential fever.

Three thermometer displays are shown: one with a green backlight for normal temperature (36.7°C), one with a yellow/orange backlight for danger of fever (37.4°C), and a family portrait in the background. This visually communicates the different temperature statuses.
